Question 1

What makes MIC-6 aluminum different from standard wrought alloys like 6061?

Accepted Answer

MIC-6 is a cast aluminum plate, not a rolled alloy. This unique casting process eliminates internal stresses. While 6061 might warp or 'move' after heavy machining, MIC-6 remains perfectly flat and dimensionally stable, making it the premier choice for precision assemblies.

Question 2

What parts are best suited for MIC-6 across PREMSA’s capabilities?

Accepted Answer

MIC-6 is specifically used for base plates, high-precision assembly fixtures, index tables, and vacuum chucks. In our CNC Machining department, we leverage MIC-6 when a customer requires large-surface parts that must maintain strict flatness tolerances across their entire length.

Question 3

How does MIC-6 perform in high-speed CNC Milling and Drilling?

Accepted Answer

MIC-6 machines beautifully. Its granular structure allows for high-speed cutting with minimal tool wear and produces excellent surface finishes. Because it is stress-free, we can machine deep pockets or complex patterns into one side of the plate without the material bowing or twisting.

Question 4

Can MIC-6 aluminum be welded for structural frames?

Accepted Answer

While MIC-6 can be welded, it is generally not recommended for high-load structural welds. It is primarily a tooling material. However, it can be successfully TIG welded for non-structural applications, though mechanical fasteners are preferred to maintain the plate's precision flatness.

Question 5

What are the finishing requirements for MIC-6 plates?

Accepted Answer

MIC-6 comes from the mill with a high-quality, pre-machined surface finish (typically 20 micro-inches or better) protected by PVC film. While it can be anodized, it is usually utilized in its 'as-shipped' precision-ground state for tooling applications.

Question 6

What should engineers consider regarding the thickness of MIC-6?

Accepted Answer

Engineers should take advantage of MIC-6’s thickness tolerances, which are much tighter than standard plate. Because the material is stress-relieved, you can design high-precision components without the need for expensive secondary grinding operations after CNC machining.
